Finally an LED which can operate at over a few watts while also maintaining decent efficiency. I doubt Cree is going the multi-die route. They either figured out how to reduce droop, or they managed to make a larger die by solving the problem of hot spots/uneven current distribution.
I just found this

Is it fake or real? They claim 100W LED with 9000 lumens!!
Now all we need a reasonable sized batteries that will take that current draw and still have a 1 hour runtime.

Amazing how fast LEDs have improved, this time last year, Cree XR-E LEDs were still a dream and Luxeons were top dog.
One easy possibility is that it's a 4 dice package, with each driven at 1A. Otherwise, it would take an extreme breakthrough to drive a single 1mm^2 device at 4A and get 70+lm/W, and maintain a 3.6V Vf.
4 dice? Sure?
"A single-die LED, driven at four amps, produced 1,050 lumens in cool white and 760 lumens in a warm-white version."
It seems R-S bins are coming out soon...
(assuming the die and LED aren't as big as j-lo's *ss... )
This sounds promising! But it's only a R&D LED, so we don't know about commercial availability. I have searched the news on many websites but apparently there are no pictures, please post them if you can find some
